In this video, we're breaking down the complex world of Apache Kafka and showing you how to gain deep visibility into your event streaming architecture using Speedscale. Kafka is the backbone of modern, cloud-native systems, but understanding what's happening in production—which topics are receiving traffic, where messages are going, and how services are interacting can be a real challenge. We'll cover how Speedscale makes Kafka visualization and debugging simple by.

Ever find yourself stuck between unit tests and a full staging environment?

Using AI coding tools like Cursor is fast, but it leaves a massive question: Is the new code going to break production? We solve this by combining Cursor with Proxymock! I take a live traffic snapshot of my running app, feed it back to the AI, and instantly run realistic integration tests locally. It's the only way to get true confidence before you push. Watch the full video below!

Tired of local development using AWS SES leading to spam, cloud costs, and unnecessary API calls? When testing your app, you shouldn't have to connect to a live cloud environment just to send a test email. Learn how to set up your own local ProxyMock server to intercept and record real SES calls, so you can replay them instantly and accurately without ever leaving your desktop.

In this quick guide, Speedscale's Matt LeRay shows you how to free your local development environment from direct AWS SES dependencies. When your application sends an email during local testing, it usually triggers a live AWS transaction, leading to slow tests, unnecessary cloud costs, and sometimes even spam filter issues.
